Embodiment Construction

[0052] In order to make the purpose, technical solutions, and advantages of the embodiments of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0053] In the following, some terms used in the embodiments of the present application are explained, so as to facilitate the understanding of those skilled in the art.

[0054] (1) Heterogeneous data sources refer to data sources of different types or modes. A data source refers to a storage terminal that stores data.

[0055] (2) Data service refers to the service of adding, deleting, modifying and querying business objects to the application through the service interface.

[0056] (3) The field of the data table is used to describe the characteristics of the data table, which can be understood as the header of the data table. For example, taking the taxi driver data table shown in Table 1 as an example, the driver ...

Abstract

A data service method and device are used to solve the problems of heavy developer workload and low data request efficiency in the prior art. In this application, by encapsulating business data into business objects at the data service provider end, the data requester can access the business data by accessing the business object description model, and the data requester does not need to know the storage format and storage location of the business data, etc. , and there is no need to write corresponding data request modules, which can reduce the workload of developers. In addition, through the method of the present application, the business object description model is associated and mapped with two data table description models from heterogeneous databases, so that the data requester can request data from two databases at the same time, which can improve the data request efficiency.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a data service method and device. Background technique [0002] With the development of Internet of Things (IoT) technology, communication between people and things and between things has become possible. In the IoT scenario, with the rapid increase of communicable entities, the data types and data volumes generated by communicable entities are also rapidly increasing. For example, in the Internet of Vehicles scenario, the types of data involved may include vehicle data, user driving behavior data, map data used for driving, in-vehicle entertainment data, user point of interest data, and weather data. , and the amount of data is very large. Different types of data may be stored in different databases (such as MySQL database, HBase database, file database (such as excel file database, comma-separated values ​​(comma-separated values, CSV) file database)), w...
